DO NOT use these hand torque values if a different
torque value or tightening procedure is given for
a specic application. Torque values listed are for
general use only and include a ±10% variance
factor. Check tightness of fasteners periodically.
DO NOT use air powered wrenches.
Shear bo lts are de signed to fa il u nder
predetermined loads. Always replace shear bolts
with identical grade.
Fasteners should be replaced with the same
grade. Make sure fastener threads are clean and
that you properly start thread engagement. This
will prevent them from failing when tightening.
When bolt and nut combination fasteners are
used, torque values should be applied to the NUT
instead of the bolt head.
Tighten toothed or serrated-type lock nuts to the
full torque value.
a “Lubricated” means coated with a lubricant
such as engine oil, or fasteners with phosphate
and oil coatings.
“Dry” means plain or zinc plated without any
lubrication.
